Answer:
e. 71 dollars
Step-by-step explanation:
Peter was willing to but the wine for $45
In a year, there is an increase of $15 = $45 + $15 = $60
The interest rate of 10% of $60 = $6
Total = $66 ~ $70
Therefore, the amount he is willing to pay for the win if he buys it as investment would be 71 dollars.
